QscR, a LysR-type transcriptional regulator and CbbR homolog, is involved in regulation of the serine cycle genes in Methylobacterium extorquens AM1.

Journal of bacteriology - 1 Feb 2003

Kalyuzhnaya Marina G, Lidstrom Mary E

Abstract excerpt

A new gene, qscR, encoding a LysR-type transcriptional regulator that is a homolog of CbbR, has been characterized from the facultative methylotroph Methylobacterium extorquens AM1 and shown to be the major regulator of the serine cycle, the specific C1 assimilation pathway. The qscR mutant was shown to be unable to grow on C1 compounds, and it lacked the activity of serine-glyoxylate aminotransferase, a key...
